Curve 8520 No internet access

1. My screen faded and just turned blank (I googled it and it is called "the white screen of death"); it looks like that problem is solved now as I left the back cover and battery pen the whole night.

2. My second problem now is that after this white screen of death story, i don't have any internet access. I tried a few help sites and done all that instructions but it still doesn't want to work. My internet worked fine before the screen started turning white. My phone is about 20 months old (not even 2 years), I'm on a pre paid plan, but I still have a few days left before I have to renew the internet.
